Why Are My Olive Tree Leaves Falling Off
Trees will often set more leaves in the spring than they can support during the summer.
Why are my olive tree leaves falling off. Olive trees require plenty of bright light. This deficiency is most prevalent in heavy soils during cold and wet weather when nitrogen is less available. Yellow leaves on olive trees are problematic because they can be a sign that the tree is deficient in nitrogen or may have contracted a fungal infection. Dropping leaves are often a sign of poor health due to improper care.
But if the tree gets too dry which often happens in the winter when watering is less frequent the leaves will dry out and drop. Of course another reason why a tree would drop leaves is moisture. Nitrogen is most frequently lacking nutrient in olive trees. If the tree gets too dry it should recover when watering resumes.
Symptoms of deficiency will often disappear by early summer. Because they are fruit bearing and evergreen olive trees need plenty of water. If the soil is too dry many of the falling leaves will be yellow. Olive trees with dry falling leaves may be suffering from water issues or a disease.
If falling leaves are well distributed throughout the tree and result in a general thinning of the leaves the problem is not serious. Olive trees are evergreens to temperatures of 12 2 degrees celsius when plants are mature so any change in foliage colour should have you investigating the matter. Trees suffering from a nitrogen deficiency have yellow tinged leaves and poor growth. If most of the leaves are green especially if you ve had the tree for several months the soil may be too wet.
Heat and drought stress will cause the tree to lose leaves that it cannot support with the available soil moisture.
